Manually Install Pacman Binaries

I'm sorry that this may not be directly related to the MSYS2 project. But I'm hoping I can get some insight here since I am working with an MSYS/MinGW environment.

I have installed Git for Windows on Windows 10 64-bit, & I'm trying to figure out if it's possible to use pacman from MSYS2 project with it. Turns out, Git for Windows comes with a MinGW/MSYS environment, but no package manager. I'd prefer to only have one MSYS environment on my system. If worse comes worst, I'll just uninstall Git for Windows & create a regular MSYS2 environment. But if I can, I'd like the try & use pacman with my current Git/MinGW/MSYS environment.

I downloaded the latest 64-bit MSYS2 tarball package & extracted its contents. I've copied the /usr/bin/pacman.exe executable, /var & /etc/pacman.d directories, & /etc/pacman.conf file to the Git/MSYS environment.

I turned off my firewall & opened the MinTTY/Bash terminal that came with Git using administrative privileges. I ran pacman & got some complaints. I don't remember what the original complaints were, but I ended up doing the following to try & add the MSYS2 public PGP key as trusted:

# gpg --recv-keys 5F92EFC1A47D45A1

Not sure how to get it to accept the key. Something is missing or not set up right. I may ask for help over at the Git project as well.

EDIT: It was suggested to me to use pacman-key for adding the public key because pacman uses its own keyring. So, I did the following but am still getting the same error:

Thanks @AntumDeluge for your steps! I just used them to install pacman in my Git for windows hosted on the new GitHub Actions. The only thing I could not do was your last step asking to run $ for PKG in $(pacman -Q | ... because on my system pacman -Q returns empty. Because of this, I have to always install the packages with pacman -S --overwrite='*' (The --force parameter for pacman was deprecated in favor of this --overwrite thing).

Another different thing I did was to download the mirrors list and the keyrings directly from the msys2 repository and unpack them directly on the %programfiles%\Git directory. So, I do not need another msys2 installation to copy them from.

I also suggested to them to ship Git for windows SDK instead of just the standard Git for windows with no a package manager, so they can stop installing the mingw environment with choco install mingw (another thing which does not have a package manager!).

This is the script/steps I used for the GitHub Actions:

### Update After seeing (https://github.com/actions/virtual-environments/pull/585 - Install MSYS2 to Windows), now I am using `set "PATH=%programfiles%\Git\usr\bin"` because sub-bash calls by bash could be using other bashes on the system PATH. ### Update 2021-10-22 It seems that now pacman uses the format zst: 1. `curl -O http://repo.msys2.org/msys/x86_64/pacman-mirrors-20210902-1-any.pkg.tar.zst` (https://www.msys2.org/news/#2020-06-29-new-packagers) 1. `tar -I zstd -xvf pacman-mirrors-20210902-1-any.pkg.tar.zst -C /` or `pacman -U pacman-mirrors-20210902-1-any.pkg.tar.zst` (https://stackoverflow.com/questions/45355277/how-can-i-decompress-an-archive-file-having-zst-or-tar-zst) Fix the error `error: libevent-devel: signature from "David Macek " is unknown trust` (https://github.com/msys2/MSYS2-packages/issues/2343#issuecomment-941815336) 1. `pacman -Syu` (and cancel upgrade with n) 1. `rm -rf /etc/packman.d/gnupg` 1. `pacman-key --init` 1. `pacman -S msys2-keyring` 1. `pacman-key --populate msys2` Installing tmux: ``` git clone https://github.com/msys2/MSYS2-packages/ cd MSYS2-packages/tmux vim PKGBUILD # and replace `_base_ver=3.2` by `master` # and replace the first line of `sha256sums=('29123123...'` # by the sha256 of the file https://github.com/tmux/tmux/archive/master.tar.gz makepkg pacman -U tmux-master-1-x86_64.pkg.tar.zst ``` Example of `tmux/PKGBUILD` ``` # Maintainer: Alexey Pavlov pkgname=tmux _base_ver=9ea971dc046ed1c5f241cf1f7b91b3a16e049225 _bugfix= pkgver=${_base_ver}${_bugfix} pkgrel=1 pkgdesc='A terminal multiplexer' url='https://tmux.github.io/' arch=('i686' 'x86_64') license=('BSD') conflict=('tmux-git') replaces=('tmux-git') depends=('ncurses' 'libevent') makedepends=('ncurses-devel' 'libevent-devel') source=(${pkgname}-${pkgver}.tar.gz::https://github.com/tmux/tmux/archive/${_base_ver}${_bugfix/./}.tar.gz 'msys-platform.patch' 'no-check-dirs-permission.patch' 'inherit-msystem-var.patch') sha256sums=('33edcc1523436ff9e0c24d1556b6fd31ff95f7fcf6501693b99c288d748604ec' 'cf7e0f642d43fc97f7c55be41c693cceab5c891f81fcee687e918075e55cd533' '8f1938c9bcb99fba5441e11379a193c17eee582a03c04f1bde8089d58a84f44f' 'aeaea034eeefe9598a56ebfabdf21cb991b2ac39d62dca9f857d24e5bc375366') prepare() { cd "${srcdir}/${pkgname}-${_base_ver}${_bugfix/./}" patch -p1 -i "${srcdir}"/msys-platform.patch patch -p0 -i "${srcdir}"/no-check-dirs-permission.patch patch -p0 -i "${srcdir}"/inherit-msystem-var.patch cp osdep-cygwin.c osdep-msys.c #msg2 "Running autogen.sh" ./autogen.sh } build() { cd "${srcdir}/${pkgname}-${_base_ver}${_bugfix/./}" ./configure \ --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ CPPFLAGS="${CPPFLAGS} -I/usr/include/ncursesw -U_XOPEN_SOURCE" make } package() { cd "${srcdir}/${pkgname}-${_base_ver}${_bugfix/./}" make DESTDIR="${pkgdir}" install install -d "${pkgdir}"/usr/share/licenses/tmux install -m 644 COPYING "${pkgdir}"/usr/share/licenses/tmux #install -d "${pkgdir}"/usr/share/tmux #install -m 644 examples/* "${pkgdir}"/usr/share/tmux #install -d "${pkgdir}"/usr/share/vim/vimfiles/syntax #install -m 644 examples/tmux.vim "${pkgdir}"/usr/share/vim/vimfiles/syntax #install -d "${pkgdir}"/usr/share/bash-completion/completions/tmux #mv "${pkgdir}"/usr/share/tmux/bash_completion_tmux.sh "${pkgdir}"/usr/share/bash-completion/completions/tmux } ```
